在軋機設(shè)置了上軋輥動態(tài)軸向調(diào)整。軋機調(diào)零后，可以測量和存儲上探頭到上輥軸及下探頭到下輥軸的距離。軋制過程中立輥如失去平衡而引起上輥或下輥的竄動，上輥會與下輥同步調(diào)整，從而保證上、下腹板對中并控制腹板和翼緣的尺寸。

There is a dynamic axial adjustment of the upper roll on the universal rolling mill. After the rolling mill is zero, the distance between the upper roll shaft and the lower probe can be measured and stored. During the rolling process, if the neutral rolls lose balance, the upper roller or the lower roll will move. The upper roller will synchronize with the lower roller, so as to ensure the upper and lower plate alignment and  the dimensi of web and flange.

機架是軋鋼機的主要部件，它在軋鋼過程中承擔(dān)金屬變形給予的負荷。因此要求機架有足夠的強度和剛度，以保證設(shè)備安全和產(chǎn)品質(zhì)量。型鋼軋機的機架形式較多，常見的機架形式有開口式機架、閉口式機架和半閉口式機架3種。

The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to have sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.

四棍軋機的工作輥直徑較小，傳遞軋制力矩，軋延壓力由直徑較大的支承輥承受。這類設(shè)備的主要優(yōu)點是相對剛度較大，壓下量大、軋延力小，可軋制較薄的板材，也包括有可逆和連軋兩種。

The working roll diameter of the four bar mill is small, and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness, large reduction, low rolling force, thin rolled sheets, and reversible and continuous rolling two.
